Android Webview - 当你 getPackageName it Fatal 时

问：

@Override
public String getPackageName() {
    if(!TextUtils.isEmpty(Bridge.sFakePkgnameCallstack)){
        StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();
        for (int i = 0; i < stackTraceElements.length; i++) {
            String clsname = stackTraceElements[i].getClassName();
            if(clsname.matches(Bridge.sFakePkgnameCallstack)) {
                Log.d("Application", "getPackageName:" + Bridge.sFakePkgname + " stack:" + stackTraceElements[i].toString());
                return Bridge.sFakePkgname;
            }
        }
    }
    return super.getPackageName();
}

该问题是间歇性的，仅在某些设备上发生。例如，我们的测试设备：Samsung SM - A520F Android 8 （SDK 26） - Webview Chrome 90.0.4430.82

该问题发生在我们 2022 年 1 月发布的应用程序版本中。
